I still have problems with apparmor after installing main, telegram Flaptak couldn't start. The solultion is sudo apparmor_parser -R /etc/apparmor.d/bwrap-userns-restrict. Should we add this to our packaging or is this another issue?

@lenemter Ah yeah we probably need to add a post-inst to make sure to remove the old profile
